Hi,
I'm trying to combine a couple of general types (associative
array, struct) in a compound data structure, but without success.
Here is what I'm trying to achieve:
"param" is a string variable
"parameters[param].id" is an integer value
"parameters[param].value" is a string value
param can be any of a fixed set of string values, all literals
known at compile time.
parameters needs to be pre-populated with all of its keys during
initialization, because they will be used to validate the param
values that are read from a file (by checking if "param in
parameters" is true).
I started with the following declarations:
struct Parameter {
int id;
string value; }
Parameter[string] parameters;
string param;
But then I simply could not come up with a way to initialize the
keys of parameters. I tried using assignments as well as enum,
but always received either a compile or a runtime error.
(Unfortunately the error messages did not enable me to find a
solution.)
Note also that the defaults for id and value are fine (int and
string defaults). But is it even possible to add the keys alone
to parameters, without assigning something?
I would welcome a suggestion for how to initialize the keys of
parameters. As there will be a couple dozen of the param string
keys, a more succinct method would be preferable over a verbose
one.
I realize that this is a very basic question, but I'm stumped!
Thank you in advance for your help.
